Comparing him to these people, i estimate that Ralph seems to be around 320 pounds or 145kg
Realistic gunt proportions (i think atleast?)
A big bottle of makers mark is 1 litre and costs 38 dollars.
33.8 oz to a litre.
2322 kcal to a litre of makers mark.
According to
National Institute on Alcohol Abuse and Alcoholism a drink of hard liqour is definded as 1.5 oz and if you drink more then 4 drinks a day then you are an alholic.
Generaly people say that it can vary from 4-22 drinks a day deping on how big of an alcoholic you are.
So lets say Ralph is a midtier alcholic and sucks down 14 drinks a day or 21 oz a day.
Thats 1445 calories or 23.5 dollars.
But you can“t live of makers mark alone.
Food intake varies but for a big boi like ralph eating next to nothing proably looks something like this:
He proably starts his day off with a sandwich, lets go with 2 ham and cheese sandwiches totaling to around 700 or so calories.
Then lets say he eats a fastfood meal. Lets say a day big mac co with fries and soda its around 1100. 1800 total.
1800+1445=3245. So the gunt is growing just at a slow speed
